Description
Historical researches on non-Darcy effects based on the Forchheimer's equation are reviewed under the needs for modeling unsaturated water flow and heat transport in highly permeable porous media. The estimation equations for the Forchheimer's coefficients a and b, proposed by Ergun (1952), Kovács (1981), Ward (1964) and Kadlec and Knight (1996) are compared. Significant differences are found in the plots of hydraulic gradient and water velocity among the equations, while the Ergun and Kovács's show almost identical. The Forchheimer's coefficient b derived from the regression of experimental data by Sidiropoulou et al. (2007) and the coefficient b derived from the measured hydraulic conductivities are not in good agreement while the Ergun and Kovács equations are relatively close to the experimental data.
